Here's another one: "Rarely has any Administration achieved what we have achieved… Not even close!"

But can you think of an actual piece of major legislation that Donald Trump has delivered?

His own headline-grabbing promises - repealing and replacing Obamacare, reforming the tax system, building that wall - have yet to materialise.

His big announcements on things like the Paris climate accord and deporting 800,000 child migrants came with qualifications and promises to negotiate down the line.

His travel ban on a number of Muslim-majority countries has been held up in the courts and his promise to thwart North Korea's nuclear ambitions is looking shaky to say the least.

Those Executive Orders, signed with such a flourish, have actually proved to have very little substantive weight.

Aside from policy, his decision to fire the FBI director brought about the appointment of a special counsel to investigate those Russia connections, a development which puts him in far greater jeopardy.

He did sign a bill on improving care for military veterans, a rare example of a chronically-divided Washington coming together for the benefit of the people it serves.

So, yes, as he tweeted, bills have been passed, although pundits say most are pretty minor. Spending on the military and the border has been increased although measuring the impact will take a while.

Unemployment continues to fall, as it has for years, and the stock market booms, and Trump claims credit for both.

He did, without doubt, achieve "SC" - appointing a Supreme Court justice - but, as a Republican president with a Republican-controlled Congress and a gap to fill on the bench, that was hardly a 'Man on the Moon' moment.

And perhaps, when we ask what the 45th president has actually achieved, that is the clearest answer: he continues to thrill and delight his core support.Greg Milam

It was however something very dear to the hearts of his base. Countless voters told me that the Supreme Court pick was the single biggest factor in deciding who to elect last year.

And perhaps, when we ask what the 45th president has actually achieved, that is the clearest answer: he continues to thrill and delight his core support.

When he says he is achieving more than anyone ever, they tend to believe him. Whatever the facts might argue.

To comfort themselves, he and his supporters label the sort of thing I have written here as "Fake News Suppression".

But, to borrow part of that famous old US election favourite, "are they better off now" than they were pre-Donald Trump?

Do they feel secure about the future of their healthcare, the taxes they'll pay, whether Kim Jong Un can nuke them? Do they trust he can work with a Congress he derides?

It still isn't clear whether Trump's ambition amounts to anything more than dismantling everything Barack Obama built. There is as yet no sign of Trump Doctrine emerging.

In Trump's mind - if we can judge that from his tweets - he still thinks he is winning.

We can also assume that he thinks America is, as he promised, winning again.

If so, in Trump logic, there must also be some losers. So, who are they?

The tragedy is that a lot of them will be very same people who still see him as their saviour.
